Embodiment 1
[0043] Example 1 Rapid detection of lactoperoxidase
[0044] The test paper detection method of lactoperoxidase in the raw material milk of this embodiment is carried out according to the following steps:
[0045] (1) Preparation of test paper soaking solution: respectively prepare 0.1mol / L citric acid-0.2mol / L disodium hydrogen phosphate buffer solution with a pH of 5.0, a TMB solution with a concentration of 22mmol / L, and Tween-20 with a mass fraction of 0.5% Solution: Mix the above three prepared solutions according to the volume ratio of buffer solution: TMB solution: surfactant solution = 40:1:2, shake for 3 minutes and mix well, which is the test paper soaking solution;
[0046] (2) Prepare H 2 o 2 Solution: prepare H with a concentration of 0.6mmol / L 2 o 2 solution.
[0047](3) Preparation of test paper: Soak the cut medium-speed quantitative filter paper strip (3cm×5cm) in the soaking solution prepared in step (1) for 1 to 3 minutes. After it is completely soaked,...
Embodiment 2
[0052] Example 2 Rapid detection of lactoperoxidase
[0053] The analysis and testing method of lactoperoxidase in the raw material milk of the present embodiment is carried out according to the following steps:
[0054] (1) Preparation of test paper soaking solution: prepare respectively a 0.1mol / L citric acid-0.2mol / L disodium hydrogen phosphate buffer solution with a pH of 4.8, a TMB solution with a concentration of 20mmol / L, and a CTAB solution with a mass fraction of 0.3%; Mix the above three prepared solutions according to the volume ratio of buffer solution: TMB solution: surfactant solution = 45:1.5:1, shake for 3 minutes and mix well, which is the test paper soaking solution;
[0055] (2) Prepare H 2 o 2 Solution: Prepare H with a concentration of 0.8mmol / L 2 o 2 solution.
[0056] (3) Preparation of test paper: Soak the cut medium-speed quantitative filter paper strip (3cm×5cm) in the soaking solution prepared in step (1) for 1 to 3 minutes. The lactoperoxidase...
